ADOLF MALINOWSKY, or 'rimoor, PENNSYLVANIA.

COAL-MIXING 'cnUTE.

7 '0 all whom it may concern:

. Be it known that I, ADQLF MALINOWSKY, a citizen of Russia, residing at Throo in the county of Lackawanna and State of ennsyl-' vania, have invented certain new and useful Improvements in Coal-Mining Chutes, of

- vice providing for a continuous freepassage of the coal or ore as long as the same is supplied tothe device. p

A further ob]ect of the invention is the provision of a chute for supplying goods or products to a carrler, the arrangement being such that the chute will be prevented from clogging during the filling operation and will supply a substantially continuous stream of the goods to be loaded during the operation of the device.

With these general objectsin view, the inventi'on consists of the combination and arrangement of parts hereinafter fully described and illustrated in the accompanying drawings in which like reference characters designate corresponding parts throughout the several views.

Figure 1 is a vertical sectional view through a portion of a mine illustrating a car positioned for loading by means of my invention, a portion of the latter being omitted;

Fig. 2 is a top plan view of. the invention with portions of trough members and the retaining posts broken away;

Fig. 3 is a side elevation of the invention,

the trough members being omitted;

Fig. 4 is a vertical longitudinal sectional view taken upon line IVIV of Fig. 2;

Figs. 5 and 6 are vertical detail sectional views taken upon lines VV and VIVI, respectively, of Fig. 2;

Fig. 7 is a longitudinal vertical sectional "view through the vibrating chute forming a part of the invention; and

Fig. 8 is a vertical transverse sectional view of the same.

Referrlng more in detail to the drawings, I have shown a portion of a horizontal mine chamber 10 for purposes of illustrating the operation of my vibrating chute 11 in connection with a stationary trough 12 for fill- Specification of Letters Patent.

14 at the bottom 15 of the mine.

The vibrating chute 11 is trough-shaped.

having one end freely positioned for longitudinal movement within the adjacent end portion ofthe trough 12, while the opposite. end of the chute 11 maybe positioned within a further trough section 12' when the siie of the mine will. permit. Substantially U- shaped brackets 16 are adaptedto support the chute 11 by means of chains 17 suspended as at 18-from the roof 19 of the mine and attached to the free ends of said brackets 16.

In this manner, it will be seen that when coal or ore is deposited into the chute 11 and the chute is reciprocated longitudinally, the ore will be caused to travel downwardly into the forward trough 12 and thence into the car 13. It will be seen that the chute 11 is slightly inclined toward the trough 12 and that the other trough 12, when employed, will supply ore to the chute 11, while the miners will throw the coal or ore to be loaded into either the chute 11 or the said troughs 12 and 12.

A base 20 is provided with a motor '21 conbe seen that during the continuous operation of the motor 21 in either direction. p E

The crank 23 is operatively connected to the rod'24 by means of an eccentric in the form of a disk 30 having a two-part strap or collar 31 inclosing its periphery and with said rod 24 pivoted as at '32, to the said strap. The wrist portion 33 of the crank 23 is journaled at one end in thearm 34 of the crank portion to which the chain 22 is oper atively connected. by means of a gear 35 secured thereon, while the opposite end of the wrist 33 is journaled in an arm 36 mounted to revolve upon a stub shaft 37 carried by a leg 38 secured to the-base 20. The shaft 37 being rigid with the le -38,"'a pinion. 39 is fixed upon said shaft 3 in constant mesh with a similar pinion 40 secured to the wrist portion 33 of the crank 23.

During the operation of the motor 21 and the turning of the crank 23, the pi'nions 39 and 40 will cause the wrist 33 to revolve for turning the eccentric 30 at the same time that the eccentric and collar 31 are being carried around by the crank 23. A longer stroke for the block 25 will be obtained in this manner as well as a compound motion being in the nature of a giggering of the block 25 with its rod 14 andpitman 29 during the reciprocations thereof.

The base 20 as well as the chute 11, and troughs 12 and 12, may be moved about in the mine to suit tl'IQ TMUlIGmBHiZS of the miners in digging the coal to be loaded into the car 13. Posts 41 are adapted to be positioned upright in the mine wedged between marginal portions of the base 20 and the roof 19 of the mine for temporarily securing the base in position for operation. A substantially semi-circular shaped head 42 is provided uponthe lever 27 outwardly of the base 20 extending substantially centrally beneath the chute 11. Separate chains 43 are connected as at 44, to the opposite nds of the periphery of the head 42 and are passed over the periphery of said head in oppositedirections for attachment by means of bolts 45 with lugs 46 upon the bottom of the chute l1. 7 Take-up nuts 47 are provided upon the bolts 45, and it will be seen that during each swinging movement of the lever 27 the chute ll'will be shifted.

The movement imparted to the block 25 by the power supplying mechanism heretofore described eflects a giggering or compound shaking movement of the chute 11 during the reciprocations thereof, which movements of the chute are similar to the shaking of a sitter or screen. These movements are adapted to agitate the chute 11 in a jerky manner for causing the contents thereof to travel downwardly into the trough 12 and insuring the fprced travel of the ore or coal positioned within the chute continuously therethrough and into the trough 12.

What I claim as new is:

1. A device of the class described, comprising a flexibly suspended chute, a base positioned adjacent thereto, an, operating lever pivoted to said base, an arcuate head at one end of the lever, chains secured to the opposite ends of said head and passing over the crank and the eccentric simultaneously with the operation ofthe crank.

2. A device of the class described, comprising a swinging chute, a base positioned adjacent thereto, an operating lever pivoted to said base, an arcuate head at one end of the lever, chains secured to the opposite ends of said head and passing over the'periphery of the head in opposite directions, c'0nnec tions between the said chains and said chute whereby the chute is adapted for reciprocation during the swinging movements of the lever, a crank mounted for operation upon said base having a rotatable wrist portion, operating means for revolving the crank, reciprocating connections. for said lever, eccentric connections between said reciprocating connections and the wrist portion of said crank, including an eccentric secured on said wrist portion, a pinion upon the wrist portion of the crank, a stationa pinion carried by the base in constant me l i with the wrist carried pinion adapted for automatically rotating the wrist portion independently of and simultaneously with the operation of the crank whereby compound movement is imparted to said chute.

In testimony whereof I affix my signature.

ADOLF MALINOWSKY.
